of the helicopter propellers and the pulling force of the tractorpropeller This invention also consists 1n certain'other features ofconstruction and in the comblnation and arrangement of the severalparts,

to be hereinafter fully described, illustrated in the accompanyingdrawings and speclfically pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like 01'corresponding parts throughout the several views, and in which Figure lis a front view of the invention.

Figure 2 is a top plan view, with parts in section.

Figure 3 is a vertical sectional view through the front part of thedevice, with parts in elevation.

' Figure 4 is a view similar to Figure 2, but showing a modification.

In these views, the numeral 1 indicates the fuselage of the toyaeroplane and 2 the wings thereof. An electric motor 3 is located in the8 attached to the wing and in a part of the.

wing. The upper end of the shaft, which is located in the wing, hasfastened thereto a beveled gear 9. A shaft 10 passes through thefuselage into the wings and has beveled gears 11 at its ends which meshwith the gears 9. Beveled gears 12 connect this shaft with the rear partof the shaft 4 which is driven from the motor.

As will be seen, each propeller 6 is of greater length than the width ofeach'wing and 1529. ,SerialllTo. 358,412.

said propellers 6 act to lift the plane verticall'y while the propeller5 acts to pull the plane forwardly, the three propellers being drivenfrom the single motor. If desired,

however, a second motor 13 may be used to drive the shaft 10, as shownin Figure 4.

The plane is suspended from any suitable support by the tubular member14 which has its lower end connected with the fuselage and theconductors 15 for supplying current to the motor may pass through thismember. The plane "is provided with the usual landing gear 16..

From the foregoing it will be seen that I have provided an attractivetoy which will both amuse and instruct children as well as 1 adults, forupon the starting up of the motor,

or motors, the propellers 6 will act to lift the toy off the surface onwhich it rests and the propeller 5 will pull the toy forwardly and thusthe toy will revolve in a circle and this circle will be graduallyincreased as.

the plane picks up speed. Of course, thepropellers 6 will help to drivethe plane forwardly as the plane assumes an inclined position as itpasses around its circular path.

' As before stated, the toy will be instructive in illustrating theaction of the helicopter propellers in lifting the plane vertically andthe pulling action of the propeller 5 so that the toy is instructive aswell as amusing.

It is thought from the foregoing descrip- I tion that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be madein the construction andin the combination and arrangement of the several parts,

provided that such changes fall within the scope of the appended claim.

What I claim is: A toy aeroplane comprising a hollow body, an electricmotor mountedinl-thebody upon the upper side of the bottom thereof and.near' the forward end thereof and including a forwardly through the forshaft extending ward end of the body and rearwardlybeyond the motor, apropeller mounted upon the forward end of the shaft, a bevel gearmounted upon the rear end of the shaft, a flexible current conductorconnected with the upperside :2 g p I 1,793,368

of the body in rear of the motor and above 7 the rear end of the saidshaft, to supply current to the motor, hollow Wings extending f fromeach side of the body, a shaft, rotatably mounted in the Wings, a bevelgear upon the shaft meshing With the bevel gea r. upon the motorsha'ft,-shafts 'journalled in the under sides of the Wings and havingtheir upper ends extending into'the ings, abevel gear upon the upper endof each of saidshafts, I V bevel gears upon the outer ends of thesecondmentioned shafts, meshing With the gears upon the last mentionedshafts and helic'op ter propellers mounted upon the lower ends of thelast mentioned shafts.

' In testimony whereof I affix my signature.
